Today’s Tech Spot Roundup
Tofu brine could power safer batteries that last decades, researchers say
The design replaces the complex, flammable chemistry of lithium-ion batteries with an electrolyte that’s as safe as saltwater. In lab tests, the prototype endured more than 120,000 charge cycles, an endurance record that far exceeds today’s commercial standards. Typical electric-vehicle batteries degrade after just a few thousand cycles – even…
Colorado bill could criminalize possessing 3D gun files, not just printing them
Colorado’s HB26-1144 bill would expand the state’s firearms rules to cover “3-dimensional printing,” defined to include additive printing and subtractive manufacturing (CNC milling is covered, too).
The Interim Computer Museum puts 28 classic computer systems on the internet for you to try
Through a partnership between the Interim Computer Museum (ICM) and SDF.org, twenty-eight vintage computing systems – some emulated, some partially hardware-based, and some running on original machines – are now accessible to the public through a web portal.
MIT's new 3D printer can create a working electric motor in one go
The team, based at MIT’s Microsystems Technology Laboratories, demonstrated the system by printing an electric linear motor – the type that generates straight-line motion instead of spinning a shaft.
Lab-grown brain tissue successfully solves a classic AI training problem
In a small lab at the University of California, Santa Cruz, clusters of mouse brain cells have taken on a task normally reserved for computer algorithms: keeping a simulated pole balanced upright. The experiment, which used real biological tissue to tackle a classic test problem in control engineering, shows that…
Sam Altman compares AI energy use to the cost of "training" humans, says water-usage concerns are "fake"
Altman launched his tirade at the India AI Impact summit during an interview with The Indian Express.
11 Need-To-Know Tools in Microsoft PowerToys
Microsoft PowerToys packs more than 30 utilities into a single toolbox, but not all of them are worth using. These 11 stand out as genuinely useful, and a few others you can safely ignore.
